azathioprine + rituximab + mycophenolate mofetil + prednisone

This is a combination immunosuppressive therapy used for treating various autoimmune conditions. The combination includes: - **Azathioprine**: A purine analogue that hinders purine synthesis and becomes incorporated into DNA during the anabolic process, inhibiting lymphocyte proliferation. - **Rituximab**: A B-cell depleting anti-CD20 antibody that targets and eliminates B cells. - **Mycophenolate mofetil (MMF)**: Works by blocking the de novo synthesis of DNA, thereby inhibiting the proliferation of lymphocytes. - **Prednisone**: A corticosteroid that reduces inflammation and suppresses immune system activity.
